Mars and 134340 Pluto will make a close approach, passing within 0°01' of each other.
From Cambridge, the pair will be difficult to observe as they will appear no higher than 17° above the horizon. They will be visible in the dawn sky, rising at 03:49 (EDT) – 2 hours and 54 minutes before the Sun – and reaching an altitude of 17° above the south-eastern horizon before fading from view as dawn breaks around 06:03.
Mars will be at mag 0.9; and 134340 Pluto will be at mag 15.1. Both objects will lie in the constellation Sagittarius.
They will be close enough to fit within the field of view of a telescope, but will also be visible through a pair of binoculars.
A graph of the angular separation between Mars and 134340 Pluto around the time of closest approach is available here.
The positions of the pair at the moment of closest approach will be as follows:
|Object||Right Ascension||Declination||Constellation||Magnitude||Angular Size|
The coordinates above are given in J2000.0. The pair will be at an angular separation of 68° from the Sun, which is in Pisces at this time of year.
